IMPROVEMENT IN MACHINES FOR FEEDING PLATES T0 SHEARINGMACHINES.

Srnclnrcn'rron.

Be it known that I, FELIX Wrzsrwoon, of Sont-hVVheel'ing, in the countyof Ohio and State of West Virginia, have invented a new and usefulmachine for feeding nailplate shears, with the iron plates to be sheared'into nailplates, in such a way as to be self-acting; and I do herebydeclare the following to be a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawing making a part of this specication, in which- Figure l isa front elevation, and Fig. 2 a side eleva-tion.

A represents the frame of the machine 5 B B, the rolls, actuated by anarm, O, through a ratchet-wheel, D, and pawl E. The arm U is connectedto the shears by means of a rod, F, and crank-pin or other suitableattachment. The arm C is so arranged that a longer or shorter stroke isgiven to it by moving the rod F nearer to or further from the centerupon which the arm C is pivoted, thereby varying the amount of feedgiven to the iron sheet or plate G, passing through the rolls B B to theshears. The machine is secured to the shears at H, and is so arrangedthat by detaching the bolts the whole machine may be turned over on theshaft I to giveaccess to the shears. J is a spring attachment to theratchet-wheel D to prevent back motion. distance between the rolls. L isa spring, bearing equally on the blocks M M, in which the top rollworks. N is a. table or rest for the iron before passing through therolls. The rolls have journals, which work in the blocks M M sliding inthe frame A A.

The iron G is put between the rolls, and is fed by the machine, atregular intervals and regular distances, by means of the ratchetthat isseparate and distinct from the frame of the nail-plate shears, and whichis connectedI to a rack or table by a hinge-joint, so that it may beturned back and thus leave space between itself and the nail-plateshears for the workman to pass between the two, for the purposes setforth.
